FURNACE WALL..

Application led April 2,

My present invention relates to improvements in furnace walls, and particularly of the type in which air-cooling spaces are provided on the exterior. of the wall through 6 which air may be passed to cool the Wall,

and will best be understood from the following description and the annexed drawings, in which Fig. 1 is a. view from the inside of a portion of a wall embodying my l invention; Fig. 2 is a section -on the line 2 2 of Fig. 1; Fig. 3 is a section on the line 3-v-3 of Fig. l; Fig. 4 isan enlargement of a portion of Fig. 3; Fig. 5 is a view similar to` Fig. 1, but showing a modificaf tion; Fig. 6 is a section on the line 6-6 of Fig. Fig. 7 is a section on the line 7 7 of Fig. 5; Fig. 8 is an enlargement o f a portion of Fig. 7; Figj9 is a view similar to Fi g- 3, but showing a modification; Fig. 10

is a section on the linelO--lO of Fig. 9; Fig.

11 is an enlargement of a portion of Fig. 9y

and similar to Fig. 4, but showing a modification; Fig. 12 is a view similar to Fig. 1

and showing still another modification; Fig.

13 is a section on the line 13-13 of Fig. 12;

Fig. '14 is a. section on the line .14--14 of Fig.`

12; Fig-15 is an enlargement of a portion of Fig. 14, and Fig. 16 is a section'on the line 16-16 of Fig. 15.

Like reference characters indicate like parts throughout the drawings.

It will be understood that in each of the constructions illustrated,while I have shown onlya portion of a wall in eachcase, the entire wall, regardless of its extent, will be made up of duplications of the portion illustrated and that in a furnace having, say, a rectangular cross-section, as 'many ofl the vertical walls of the furnace as is desired may be made up in the manner illustrated.

In the arrangement shown in "Figs 1 to 4 inclusive, the wall roper 10 is'made up of the usual courses o refractory brick or tile, as the case may be, the Wall being provided with one or 'more courses of special tile 11, which, in the form illustrated, are rovided with grooves, so that when a pair o the tiles 11 are placed side by side, a T-shaped groove is provided with the neck of the groove extending to the rear of the tile and the en-l largement between the front and the rear of the tile. It should also be noted that while I refer to this recess as T-shaped any form of recess in which there is an enlargement between the front and the rear of the 1925. Serial No. 20,026.

tile is to be'understood as being covered by that phrase.

Outside of the wall and extending vertically is a series of spaced fixed members which, in the form shown in Fig. 1, are I- beams 12 having a web of suiiicient height so that when one fiange of the I-beam is against the refractory Wall, the other Vflange will be sufficiently spaced therefrom to provide the desired width of air duct on the outside of the refractory wall. The space between the I-beams 12 is filled with a casing 13, and, as will be best seen by an inspection of Fig. 3, each pair of I-beams 12 with .the casing 13 and the refractory Wall constitutes a vertical air duct througlrwhilch air may pass to cool the outside of the Wall.

In the recesses formed between each pair of tile 11" is a bulb piece 14 with an enlarged head 15 engaging the enlarged inner end of the recess and with the shank of the bulb piece extending through the narrow partof the recess and into the air duct just referred to.` The outer end ofthe bulb piece is provided with a hook portion 16, the recess of which preferably extends vertically to the'top of the bulb piece 14. In this recess 'of the hook Vrests 'a horizontal .bar 17 which, in the form shown in Figs. 1 to 4, inelusive, is simply a bar of rectangular crosssection. The recesses forming the hooks 16 are positioned in the several bulb pieces so that, when the bar 17 rests behind the hooks 16, its ends Will be positioned against -the inner surface of that flange of the I-beam 12 whichl contacts with the refractory Wall. Preferably the tile 11 and the bulb pieces 14 are of approximately the same height, though, if desired, the bulb pieces may be made of aless height to permit vertical motion thereof in the tile 1l.

In the arrangement described, the wall is free to expand in any'direction. in a vertical plane, the lateral expansion being permitted y the sliding of the bulb 'pieces 14 along the horizontal member 17.. The vertical moward motion and yet' be free to move in anyy this form, the fixed I-beams 18 ext-end horizontally in spaced relation, the casing 13 and the wall 1() forming the other sides of the horizontal air duct. At spaced intervals I have shown fixed vertical members 19 each made up of al pair of angle-irons with their' ends connected through suitable angles with the horizont-al I-beams 18. As before, the ends of the horizontalbar 17 rests against the inner side of that flange of the fixed members 19 which is against the refractory wall and the bar 17 is free to slide on this flange to permit the desired vertical motion of the wall, the desired horizontal motion being provided as before by the sliding of the -bulb pieces 14 on the bar' 17 and the bar 17 by its contact with the fixed members 19, preventing the motion of the wall toward the furnace.

In each of the arrangements just described, the wall is held only against motion toward the furnace except where it bears on the fixed members. In some cases, it is desirable to hold it more effectively against Jossible outward motion by holding each of the special tiles 11 against such outward motion. This I provide for in the arrangement shown in Figs. 9, 10and 11 by attaching to the web of the I-beam 12 an angle piece 20 abutting against the outer side of the bar 17 and, therefore, preventin the motion of the bar in a direction away rom the refractory wall. As will be best seen in Fig. 11, the bar 17 will thus be held against motion ineither direcv tion at right-angles to the surface of the wall and that of the wall, therefore, will be held against both inward and outward motionthroughout its entire width. Since the ossible vertical motion of the bar 17 is a s ort one, the angle pieces 20` need have no con` siderable height, as shown in Fig. 10.

In Figs. 12 to 16, inclusive I have shown an arrangement for holding the wall against horizontal motion in either direction, in this case, the horizontal bar 21 being formed of an angle-iron, one flange of which restson the hook recess of the bulb iece 14 and the other rests on top of the hoo s 16. The ends of this angle-iron are held between the flanges of'the small vertical I-beams 22 -and angle pieces 23 attached to the web of the' I-beams 22. In this arrangement, the air ducts are horizontal and'are formed by the casing 13, the refractory wall and the fixed horizontal I-bea'ms 24, tor which the vertical I-beams 22 are attachedin any suitable manner.

It will be understood that the arrangements which I have shownare merely illustra-tive and that the embodiment of my invention may be widely varied.` It will also be understood that while I have described Lthe usual arrangement in which the courses of special tile 11 extend horizontally, these courses may be made to extend vertically, in which case the entire arrangement would be turned through 90, and I intend in the appended claims to coversuch an arrangement.
